A(1) = 2
r = a(2)/a(1) = -8/2 = -4
![a(n) =a {(r)}^{n - 1} \\ a(n) = 2 {( - 4)}^{n - 1}](https://tex.z-dn.net/?f=a%28n%29%20%3Da%20%7B%28r%29%7D%5E%7Bn%20-%201%7D%20%20%5C%5C%20a%28n%29%20%20%3D%202%20%7B%28%20-%204%29%7D%5E%7Bn%20-%201%7D%20)

Answer:
![\frac{5}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B3%7D)
Step-by-step explanation:
Given that the triangles are similar then the ratios of corresponding sides are equal.
To determine the scale factor calculate the ratio of corresponding sides, that is
=
= ![\frac{5}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B3%7D)
Answer:
Step-by-step explanation:
Answer:
The answer is 6z-28
Step-by-step explanation:
20 - 3[4(z+1) - 6(z-2)]
= 20 - 3(4z+4-6z+12)
= 20 - 3(16 - 2z)
= 20 - 48 + 6z
= 6z - 28
You need to set the correct porportion. x is the percent value you want to find. 100 is the maximum percentage. 420mg is what was taken out of the maximum 560mg dose.
![\frac{x}{100} \times \frac{420}{560}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%7D%7B100%7D%20%5Ctimes%20%5Cfrac%7B420%7D%7B560%7D%20)
You will cross multiple.
![560x = 42000](https://tex.z-dn.net/?f=560x%20%3D%2042000)
you will divide 42000 by 560
![\frac{560x}{560} = \frac{42000}{560}](https://tex.z-dn.net/?f=%20%5Cfrac%7B560x%7D%7B560%7D%20%3D%20%5Cfrac%7B42000%7D%7B560%7D%20)
![x = 75](https://tex.z-dn.net/?f=x%20%3D%2075)
The complete answer will be: The patient took 75% of the 560mg dose of medication.
